In Figures 1 to 8 inclusive, the upper blank includes sides II) and I I,preferably formed integral and the side II is foldable upon a transverseline I2. The side I I has longitudinal slits or slots I3, arranged nearand spaced from its longitudinal edges, and these longitudinal slotsterminate short of the ends of the side I I.

The lower blank includes an intermediate side I I having end sides I5and I5, preferably integral therewith and foldable upon transverse linesI! and I8, respectively. The intermediate side Id has longitudinaltongues I9 at its longitudinal edges, foldable upon longitudinal lines25.

The side I5 has an inner tapered portion 2| and an outer laterallyreduced portion 22, having locking tongues 23. These locking tonguesinclude ends 24 and 25. The ends 25 are separated from the taperedportion 2| by slits or slots 25.

The side It is provided near its free end with a socket 21 of a snapfastener, the companion stud 28 of the socket being secured to thetapered portion 2 I, as shown.

1n assembling the elements of the pocket construction, the side I0 isplacediupon the side I 4 and the longitudinal tongues I9 are foldedinwardly over the longitudinal edges of the side Ill, Figure 3. The sideII is then folded upon the transverse line I2 and is arranged over thetongues I9. The overlapping side II, tongues I9 and side III are securedtogether by lines of stitching 29, passing through these parts but notpassing through the side I4. eifected by a tubular work sewin machine.If desired, the side II may first be folded over the side Ii! and onetongue I9 inserted between these This stitching may be 7 sides and thesides I I and In swung to an open fiat position, whereby side It, tongueI9 and side II may be stitched together when in the open flat position,subsequently to which the folded sides I I and III are then swung overthe side It, and the other tongue I9 passed between the sides II and I0and stitched to these sides by the tubular work sewing machine.

With the parts thus connected, the side 22 is now folded over the sideII and the locking tongues 23 are passed inwardly through the slits orslots I3, and the ends 24 and 25 engage beneath the side II, thussecurely detachably connecting the side 22 with the side I I. This isillustrated in Figure 5. To completely close the pocket con struction,the side I6 is folded over the side 22 upon the transverse line I8 andthe socket 27 detachably receives the stud 28,

The side It forms with the side I4 a pocket 30, which extends throughoutthe entire width and length of the side I4, Figures 7 and 8 and has bothends open. The outer end'of this pocket 35 is covered by the side Itwhen this side is in the closed position and access may be had to theouter end of this pocket by opening the side IS. The side It forms withthe side II an intermediate pocket 3I, which extends through the widthof the side III to the tongues I9 and throughout the entire length ofthe side It. This pocket 3! is closed at one end at the folding lines I2and open at its opposite end. The open end of the pocket 3! is coveredby the side 22 when this side 22 is folded over the side II. Access canbe had to the pocket 3I by separating the side 22 from the side II andswinging the side 22 to the open position. The side II therefore closesthe open end of the pocket 3i. Since the side 22 is securely detachablyconnected to the side I I, the contents of the pocket 3I are protectedfrom improper removal from the pocket 3| The side 22 when in the closedposition forms with the side II a pocket 32, which is smaller than thepocket 3|. The pocket 32 has an open end next to the folding line I8,and when the side I 6 is in the closed position this side covers theopen end of the pocket 32. The open end of the pockets 35 and 32 areboth arranged near the folding line I 8 and are both covered by theclosed side I5 and by opening this closed side, access can be had toboth pockets 3i! and 32.

When in the closed position, the side It covers the lines of stitching29, and these lines of stitching are also covered by the side It, andhence the lines of stitching are not visible from the exterior of thepocket construction, when all parts thereof are closed. In someinstances I contemplate omitting the side It and associated fastener.When this is done one end of the pocket 55 will be permanentlyuncoveredwhile the side 22 will close the open end of the pocket SI andthe'openend of the pocket 32 will be permanently uncovered.

In Figures 9 to 19 inclusive I have shown a second form of theinvention. The upper blank 34 comprises a side 35 preferably formedintegral with a side 35, and the side 35 is foldable upon 'a transverseline 37. The side 35 has longitudinal slits or slots 38, spaced inwardlyfrom its longitudinal edges, and terminating short of its ends, asshown. a

The lower blank 35 comprises an intermediate side 60 and end sides 5|and 42, preferably'formed integral. The side 4| is foldable upon atransverse line 23 and the side 42 is foldable upon a transverse line54. The side 40 is provided 5. at its longitudinal edges with tongues 45foldable upon longitudinal lines 45 over the inner face of the side 45.The side M is provided at its longitudinal edges with longitudinal flaps41, foldable inwardly upon longitudinal lines 48. These flaps provide abellows formation at the longitudinal edges of the closed pocketconstruction. The flaps 41 are provided at their ends with slits 49forming locking tongues 55, spaced outwardly from the folding lines 48.The side 42 is provided near its free end with a socket element 5i of asnap fastener for receiving the companion stud element 52, attached tothe side 4| and arranged upon its outer face.

In assembling the parts of the pocket construction, the tongues 45 arebent inwardly over the inner face of the side 45 and the side 35 isarranged upon the inner face of the side 40, beneath the tongues 45,Figure 10. The side 35 is then folded over the side 35, upon the foldingline 31, and is arranged upon the outer faces of the tongues 45, Figures11, 12 and 13. The side 35, tongues 45 and side 35 are secured togetherby lines of stitching 53, passing through these parts but not throughthe side 45, Figure 12. The side M is then folded over the side 36, uponthe folding line 43, and the flaps 41 are folded inwardly upon the lines48, and the locking tongues 55 are inserted into the slots 38, wherebythe side 4|. is attached to the side 36 adjacent to its longitudinaledges. The side 41 has substantially the same width as the side 36 andby virtoe of the flaps 41 forms a pocket 54, extending throughoutsubstantially the entire width of the sides 4! and 36. This pocket isopen at its inner end and closed at its outer end. The flaps 41 formbellows constructions at the longitudinal edges of the pocket. The side35 forms with the side 40 a pocket 55, the side 35 constitutes a liningbetween the locking tongues 50 and this pocket. The pocket 55 is open atits inner end and closed at its outer end. The side 42 is foldable uponthe line 44 over the side 4|, covering theupper ends of the pockets 54and 55, the socket 5i receiving the stud 52.

Instead of using the side 42, a second unit including pockets 54 and 55may be substituted therefor.

In Figures 20 to 35 inclusive I have shown a third form of theinvention. This form of the invention embodies a bill folder havingpockets. The numeral 55 designates an integral blank comprisingintermediate sides 51, foldable upon a transverse line 58. At one oftheir longitudinal edges, the sides 5i carry inner lateral sides 55foldable upon longitudinal lines 55. The outer ends of the sides 51terminate at the outer ends of the sides 55, while the inner ends of thesides secure the inner lateral sides 59 to the sides 65 adjacent totheir opposite ends. The tongues Bl form bellows constructions, at theends of the inner lateral sides 59. The sides 59 form with the sides 65pockets '1II, closed at one longitudinal edge and open at the oppositelongitudinal edge. By virtue of the flaps 6| these pockets extendthroughout the. entire length of the sides 59'. The

sides 65 form with the sides 68 spaces or pockets 12, receiving the endsof the lining section 10, extending across the folding line 58. Thesides 58 form with the sides 51' pockets 13 and these pockets 13 areclosed at one longitudinal edge and open at the opposite longitudinaledge and have their inner ends open, so that the bills may be introducedtherein and placed upon the intermediate sides 51 and extend across the:foldingline 53.

As shown in Figure 30, the assembled bill folder is arranged in the openposition and the bills are arranged within the pockets 1?. beneath thelining section 15' and these bills correspond generally to the combinedlength of the pockets 13. When the bill folder is closed, Figure 33, itfolds upon the line 58, causing the bills to transversely fold upon thisline. Access may be readily had to the pockets 1|, adapted for holdingcards or the like. VJhen the folder is opened, as shown in Figure 30,access may be had to the open ends of the pockets 1!.

In Figures 36 to 43 inclusive I have shown a further modification of theinvention. The same. intermediate sides 51 are used, foldable upon thetransverse line 55, as shown in Figures 20 to 34 inclusive. Oneintermediate side 51 carries the same inner lateral side 59 equippedwith the flaps 5i. This side 51 carries. the, same end-side 65, in turncarrying the same outer lateral side, 68. When the sides 68, 65 and 59are folded to the assembled position, they produce. the same pocketsasdescribed in connection with Figures 20 to 35 inclusive.

The companion intermediate side 51 carries an inner lateral side 14,foldable upon a longitu- 51 extend beyond the inner ends of the sides55, as shown. Each side 59 is provided at its opposite ends withtransverse flaps 6i foldable upon transverse lines 62. The flaps 6| areprovided with slits 53, forming locking tongues 54. Formed upon theouter ends of the intermediate sides 51 are end-sides 55, foldable upontransverse lines 55. These end-sides are provided near and spaced fromtheir opposite ends with transverse slits 51, the ends of whichterminate short of the longitudinal edges of the sides 55. The endsidescarry outer lateral sides 55 foldable upon longitudinal lines 55. samelength as the sides 85. i V

Thenumeral 15 designates a lining section. In assembling various partsof the folder, the outer lateral sides 55 are ifirst folded over the Thesides 55 are of the Figures 39 and 40.

dinal line 14', provided with pairs of longitudinal slits or slots 15,arranged near and spaced from the longitudinal edges of the side 14 andspaced from its ends. The side 14 carries a second lateral side 15,foldable upon a longitudinal line 11. The intermediate side 51 carriesan endside 18 foldable upon a transverse line 19. The end-side 18 isprovided with longitudinal flaps 85, foldable upon longitudinal lines 81and these flaps have slits 81 forming locking tongues 82, spacedoutwardly from the lines 8|.

In assembling, the side 16 is folded over the side 14 upon the line 11,Figures 37 and 38, forming a pocket 83. The assembled sides 15 and 14are then folded upon the line 14' over the side 51, In this arrangementthe side it is next tothe side 51 and the side 14 is uppermost.

The side I8 forms with the side14 a pocket 85, open at its inner end. The same lining section III isinserted in the inner ends of the pockets 83. The flaps 89 form bellowsconstructions at the longitudinal edges of the pocket 84 and this pocketextends throughout the entire width of its sides.

It is thus apparent that bill receiving pockets are arranged next to thesides 51 and these bill receiving pockets are open at one longitudinaledge. The other pockets are opened at their inner ends. The bill folderis foldable upon the transverse line 58 to assume a closed-position, ina similar manner as described in connection with the form of theinvention shown in Figures 20 to 35 inclusive.

In Figures 44 to 58 I have shown a further modification of theinvention. The numeral 85 designates a main blank including intermediatesides 86, foldable upon a transverse line 9?. The sides 86 carryend-sides 89, foldable upon trans verse lines 89. The intermediate sides95 are provided at their longitudinal edges with longitudinal tongues99, foldable inwardly over the sides 86 upon lines 9!. At the outercorners of the sides 86 are small tapered tongues 92, fold able inwardlyupon the sides 86, to provide neat folded corners.

Numeral 93 designates a lining blank, including sides 94, foldable upona transverse line 95. Each side 94 has a'pair of spaced longitudinalslits or slots 96, spaced from the longitudinal edges of the sides 94and spaced from the ends cf the same, as shown.

The numeral 97 designates a pair of pockets, connected by anintermediate portion 9 3, and foldable upon a transverse line 99. Theopposite sides of these pockets are preferably formed of transparentmaterial. The inner ends of these pockets are open and are adapted toreceiving license cards or the like.

The numeral I99 designates a side, for co- .action with the right side89, Figure 44, and this side is provided at its inner end with atransverse fiap IQI, foldable upon a transverse line PE. side I99 isprovided at its longitudinal edges with longitudinal flaps I 33,foldable upon longitudinal lines, I94, Each flap is provided with pairsof locking tongues I95, as shown. At its corners, between the flaps NHand M3, the side Ill!) has small tongues I99, foldable inwardly over thesame to provide folded corners.

Arranged near the left side 88, Figure 44, is a side I96, provided atits inner end with a transverse fiap I01, foldable upon a transverseline I08. The side I99 is provided at its longitudinal edges withlongitudinal flaps I99, having pairs of locking tongues H9. The side IE5is provided with pairs of longitudinal slits or slots El 5. The slits ineach pair are spaced from each other and are spaced from thelongitudinal edges of the side I 95 and from its ends, as shown. Theside I96 is provided at its corners, between the flaps I 01 and I09,with small tongues E96, foldable inwardly to produce folded corners. Theside I05 carries a side I I2, foldable upon a transverse line H3.

For co-action with the side I99 is a side Mil, provided at one end witha flap I l5, foldable upon a line I I5. The side IN is provided at itslongitudinal edges with longitudinal flaps H5, having pairs of lockingtongues Hi. At its corners, between the flaps H9 and H5, the side II lhas small tongues H4, folded inwardly to produce folded corners.

The

'In'assembling the various parts of the device, the pairs of pockets 91are first positioned upon the lining blank 93 and these elements arestitched together at the folding lines 99 and 95 by a line of stitchingH8, terminating short of the ends of the intermediate connecting portion98, Figure 45. The pockets 9? may be shifted to the closed position andthe lining blank 93 placed upon the blank so that the sides 94 registerwith the sides 85 and the tongues 99 are folded over the longitudinaledges of the sides 94 and the tongues 99 and sides 94 are stitchedtogether by longitudinal lines of stitching H9, which do not passthrough the sides 86, Figures 46 and 47. The flap Hill of the side IE0is now arranged upon the outer or lower face of the right side 98,Figure 48, and, the flap IIlI is secured to the side 68 by a line ofstitching I20, which follows the free marginal edge of the flap I9I. Theflap I97 of the side I96 is secured to the lower or outer face of theleft side 88, Figure 48, by a line of stitching IZI, which follows thefree marginal edge of the flap I91, these stitching operations areindicated in Figure 49. In Figure 50, the right side 88 is still in theopen position with the side I99 depending from it. The left side 88 hasbeen folded over the tongues 99 and the sides I95 and H2 arehorizontally arranged. The side H4 is now depending beneath the side I96and the flap H5 is engaging the lower face of the side I96 and issecured to the side I95 by a line of stitching I22 which follows thefree marginal edge of the flap H5. This arrangement is also shown inFigure 51. As shown in Figure 52, the side I89 is now swung upwardly toengage the outer face of the side 88 and the flaps I63 are folded uponthe inner face of the side 88. The left side 89 is arranged in anupstandingposition, Figure 52. The side I95 is swung to the upstandingposition and the side H2 is folded downwardly over the inner face of theside I06 and is disposed between the side 88 and the side I96. The flapsI99 are now folded inwardly upon the inner face of the side 88. Thesides88 and I99 are now folded upon the transverse line 89 to a position uponthe right side 94, Figure 52, and the locking tongues I85 are passedinto the pairs of right slits 95. The side 98 forms with the side as apocket I22 and the side we forms with the side 88 a pocket Hi3, both ofthese pockets having openings at their inner ends, adjacent to thefolding lines 95 and 87. These pockets have a width extending throughoutthe entire width of their sides, and the flaps I93 provide bellowsconstructions at the longitudinal edges of the folder. The assembledsides 88, I95 and Iii are now swung over the left side 95, Figure 55,and the tongues III) of the flaps I99 are inserted into the pairs ofleft slits 96. The side H4 has its flaps H6 folded inwardly and the sideH4 is folded over the side I95 and the tongues I ll are inserted withinthe pairs of slits III of the side I99. The side as forms with the side94 a pocket I24 and the side 88 forms with the side H2 a pocket I25. Theside I It forms with the side Hi6 a pocket I26. These pockets have awidth extending throughout the entire width of their sides. The fiapsI09 and H6 form bellows constructions at the longitudinal edges of thedevice. The sides 9 3 cover the locking tongues I95 and III], while theside H2 covers the locking tongues III. With the parts thus assembled,Figures 54 and 55, the entire folder may be closed, by folding upon thelines 95 and 81; Figures 56, 57 and 58. It is thus apparent that I haveprovided a folder including The several blanks or parts of various formsof the invention are formed of suitable material, such as leather,artificial leather or the like.
